What is the measure of the missing angle? 40 90

Answer:

50°

Step-by-step explanation:

I am assuming that the shape is a right triangle.

All interior angles of a triangle add up to 180°.

x + 40 + 90 = 180\\\rule{150}{0.5}\\x + 130 = 180\\\\x + 130 - 130 = 180 - 130\\\\\boxed{x = 50}

The missing angle should be 50°.

Hope this helps.

Answer:

\boxed{50 }

Step-by-step explanation:

<h2><em>What is a Triangle?</em></h2>

<em>A triangle is the simplest polygon. It is a two-dimensional shape with three straight sides forming an interior, closed space. It has three interior angles. </em>

<em />

<em>1. Subtract the two known angles from 180° </em>

<em> </em>

<em> </em>

<em> </em>

<em>2. Plug the two angles into the formula and use algebra: </em>

<em />\boxed{a+b+c=180}

3. Subtract

\boxed{180-40 =140}

\boxed{140-90=50}

c=50

<em><u>Therefore, The Answer is 50</u></em>

<em> </em>

Solve for x use the completing the square method x^2+6x=5
Mrac [35]

Answer:

x_{1} =-3 +\sqrt{14} \\\\x_{2} =-3 -\sqrt{14}

Step-by-step explanation:

x^{2}+6x-5=0

we divide the coefficient of the X by half :

in this case: 6/2 = 3 , then we do the following

The result obtained is raised to square power:  3^2=9

we sum and subtract by 9 to maintain the balance of the equation:

x^{2}+6x+9-9-5=0

we have:

(x+3)^{2}-9-5=0

(x+3)^{2} = 14

lets apply square root on both sides of the equation:

\sqrt{(x+3)^{2}}=\sqrt{14}

we know:

\sqrt{a^{2}} = abs(a)

so we have:

abs(x+3)=\sqrt{14}

from where two solutions are obtained

x_{1} + 3 =\sqrt{14} \\\\x_{2} + 3 =-\sqrt{14}

finally we have:

x_{1} =-3 +\sqrt{14} \\\\x_{2} =-3 -\sqrt{14}

Confusion...help please
kifflom [539]

Given:

In triangle KLM, KL = 123 cm and measure of angle K is 35 degrees.

To find:

The length of the side KM to the nearest tenth of a centimeter.

Solution:

In a right angle triangle,

\cos \theta =\dfrac{Base}{Hypotenuse}

In the given right triangle KLM,

\cos K=\dfrac{KM}{KL}

\cos (35^\circ)=\dfrac{KM}{123}

0.819152=\dfrac{KM}{123}

Multiply both sides by 123.

0.819152\times 123=KM

100.755696=KM

KM\approx 100.8

The measure of side KM is 100.8 cm.

Therefore, the correct option is (2).

What is the measure of ABC and please show me how to do it
oksano4ka [1.4K]
Arc length from A to C (red line) is the given inside angle times 2, so AC = 50*2 = 100 degrees.

A full circle is 360 degrees, so arc ABC (blue line) would be 360 - 100 = 260 degrees.

The answer is D.
